Hi all,

How i can add sleep in my perl while loop?

i wans using the following

while(true){
print "Abdul Lateef";
sleep 2;
}

i want to delay for 2 seconds. Where i run this on console using perl i found it is sleeping for permanently and it is not giving any output.

perldoc -f sleep

Shouldn't it be sleep (2) - sleep() would sleep forever so I guess that's what it's doing.

print STDOUT is line buffered by default.
It doesn't print until a newline.

print "Abdul Lateef\n";

an important thing to remember. Especially if you start playing with sockets!

simple but confusing

hi all,

I used the for loop and the sleep 2; is working well.
